README for DynaGraph 0.2a

Finally getting another DynaGraph Release out the door.

DynaGraph now has support for Line Graphs, many thanks to Lauren Stegman
for the code :-)

There was quite alot of confusion in the last release, caused by the README
file included in that release.

I had gotten a little too far ahead of my self with that readme and misled
people into thinking that there should have been other files included in that
tar ball. Hopefully I won't make that mistake again, if I have please let me
know at michael@2bitunix.org, and I'll fix it ASAP.   ;-)

The files are:
	bargraph.php
	varlog.inc
	linegraph.php
	call-linegraph.php
	README

As this is an alpha release, the code may not work. I haven't played with the
code for linegraph.php as of yet, since I'm running Linux, and haven't had the
time to set up TrueType support yet. If you run into any problems please let
me know and I'll get it fixed.

Setup for graphing is relatively straight forward, place the *.php and
*.inc files in your web directory. If you are not running your own web server,
check with your host to see if they have PHP and MySQL support.

bargraph.php only requires some minor editing of the varlog.inc file as described
in the comments in the file. Basically you just need to supply values for the
variables, which I beleive are self explanatory.

The call-linegraph.php file shows an example of calling linegraph.php from
within a web page.

If you do not have gd <= 1.3 you should change a the ImageGIF(xxx) lines to
ImagePNG(xxx) or ImageJPG(xxx), depending on which graphics format you have
support for or prefer. This is due to patent problems with the LZW compression
format used by the gd library. In actuality though, I have found that PNG
produces smaller image file sizes than GIF does anyway.

If you would like to contribute to the DynaGraph Project send me an email and
let me know. You don't have to write code to contribute, we can always use
docs, logos, testers, etc.

Enjoy!
